In each of three experiments animals received blocking, A+ AX+, in which food was always presented after one stimulus, A, that was occasionally accompanied by another stimulus, X. They also received a simple discrimination, AX+ BX-, in which the presence and absence of food was signaled by two compounds that contained one unique cue, A or B, and one common cue, X. In each of these designs, X can be said to be redundant relative to A as a signal for food. Test trials at the end of training revealed that responding during X was stronger after blocking than after the simple discrimination. These results contradict predictions from theories of learning that assume changes in associative strength of a stimulus are determined by a global error term based on the outcome predicted by all the stimuli that are present for a conditioning trial. The results are interpreted, instead, by assuming either that animals store a memory of every trial to which they have been exposed, or that learning is governed by an error term based on the significance of individual stimuli. 相似文献

Temperamental negative affectivity (NA) and effortful control (EC) have long been of interest to psychologists, but sensory regulation (SR) has received less attention. Using confirmatory factor analysis, the present study reexamined the Rothbart model of EC and NA using the Children's Behavior Questionnaire (CBQ; M.K. Rothbart, S.A. Ahadi, K.L. Hershy, & P. Fisher, 2001), along with alternative models of EC, NA, and SR using the CBQ and Short Sensory Profile. The results failed to replicate the Rothbart model of EC and NA, which includes SR within the EC and NA factors. A good fit was found for a three‐factor model (EC, NA, and SR) that was replicated in a holdout sample. A three‐factor model also showed a good fit when EC, NA, and SR items similar to symptoms of behavior problems were eliminated. 相似文献

Conceptual analysis has not been systematically implemented in psychology, and many concepts have often been defined in different and contradictory ways. This article focuses on a conceptual clarification of ethnocentrism. It points out the conceptual confusion surrounding the term, reviews numerous definitions and operationalizations, and attempts to clarify it. Ethnocentrism is reconceptualized as a strong sense of ethnic group self‐centeredness, which involves intergroup expressions of ethnic group preference, superiority, purity, and exploitativeness, and intragroup expressions of ethnic group cohesion and devotion. It is conceptually and empirically distinguished from other concepts, such as outgroup negativity and mere ingroup positivity. The article presents a theoretical framework and related empirical analyses supporting the usefulness of reconceptualized ethnocentrism. It also details important and unique implications of reconceptualized ethnocentrism for political phenomena. It is expected that reliance on the clarified reconceptualization should enable researchers to systematically study ethnocentrism, its origins, and consequences. 相似文献

This study links Horney’s account of human growth and neurosis to authenticity by examining aggressive responses on the point subtraction aggressive paradigm, providing the first empirical test of whether authenticity can predict objective behavior. Data from undergraduate, postgraduate, and mature students demonstrate that when controlling for age, gender, trait-anger, agreeableness, and functional dimensions of coping, individuals who measure high on authentic-living respond less aggressively to attacks and counter-attacks in unfair situations. Authentic-living uniquely accounted for 14.2% of variance in aggressive-responses (r = −.37). The findings suggest that inauthenticity is a strong predictor of aggressive behavior, and therefore increasing levels of authenticity in counseling practice may reduce maladaptive levels of anger. We suggest future exploration between authenticity and models of emotional regulation will unearth the cause and effects of aggression within inauthentic individuals. 相似文献

The purpose of this study was to (1) extend the research findings of decreased muscular force production in grip strength to the lower extremity strength of children with NF1 and (2) to determine if there was a relationship between isometric strength and functional activities in children with NF1. Force production was assessed using a hand held dynamometer (HHD) and a functional task (hopping and jumping) on a force plate. Data from twenty-six children with NF1 were compared to data from 48 typically developing children of similar sex, weight and height. Children with NF1 demonstrated statistically significant lower force production with HHD (p<0.01) during hip extension, but similar force production for knee extension and ankle plantar flexion compared to the control group. A relationship existed between the ground reaction forces at take-off from both hopping and jumping and the force generated from knee extensor strength in the NF1 group. The addition of a functional task to hand held dynamometry is useful for determining a relationship between common clinical measures and functional activities. 相似文献

We assessed the combined effects of cognitive ability, opportunity to fake, and trait job-relevance on faking self-report emotional intelligence and personality tests by having 150 undergraduates complete such tests honestly and then so as to appear ideal for one of three jobs: nurse practitioner, marketing manager, and computer programmer. Faking, as expected, was greater (a) in higher-g participants, (b) in those scoring lower under honest conditions (with greater opportunity to fake), and (c) on job-relevant traits. Predicted interactions accounted for additional unique variance in faking. Combining all three factors yielded a “perfect storm” standardized difference of around 2, more than double the overall .83 estimate. Implications for the study of faking are discussed. 相似文献

The aim of the present research was to develop a measure that assessed the level of ethnic identification of adults from diverse ethnic backgrounds, as well as individuals' level of ethnic identification with a host culture following migration. In the first study, an ethnically diverse sample of 275 people (138 males and 137 females) responded to a range of new items, as well as items drawn from related scales. Factor analysis revealed three dimensions of ethnic identity that were labelled, “Pride in Ethnic Background and Language,”“Liking for Traditional and Social Activities of my Ethnic Group,” and “Sense of Belonging to This (host) Country.” This factor structure was evaluated in a second study with 1,007 (552 males, 455 females) adults from culturally and linguistically diverse backgrounds. A two‐factor structure provided the most parsimonious fit to the data but further investigation of the factor structure within ethnically diverse samples was recommended. The results are discussed in relation to theories of social identity as well as research on ethnic identification and adaptation. 相似文献
